Call treesit_record_change in insert_from_gap_1

Call treesit_record_change in insert_from_gap_1

Before this change, insert_from_gap calls treesit_record_change but
insert_from_gap_1 doesn't.  However, insert_from_gap_1 is a public
function and is called in many other places outside of insdel.c.  This
could lead to tree-sitter's parse tree becoming out-of-sync with the
buffer content.

This change might fix bug#60650.

* src/insdel.c (insert_from_gap_1): Call treesit_record_change.
(insert_from_gap): Remove call to treesit_record_change.

* admin/notes/tree-sitter/treesit_record_change: New file.
